If a demotion involves a significant reduction in duties or remuneration, it may constitute a 'dismissal', even if the person demoted remains employed by the employer.[1]
The employment contract may be repudiated by the employer when an employee is demoted, without consent, and suffers a significant reduction in pay[2] If the repudiation is accepted by the employee, either expressly or through conduct, the contract is terminated.[3] If the demoted employee remains in employment after accepting the repudiation they would be under a new contract of employment.[4]
However, a demoted employee may remain employed in the demoted position without agreeing to the demotion, that is, under protest or for financial or similar reasons.[5]
If the employee's contract or industrial instrument contains an express term allowing demotion without termination then any demotion will not amount to a termination.[6]
